OVERFLOW-TRAP FOR WASH-BASINS BATH-TUBS, 80C.

SPECIFICATION forming part of Letters Patent No. 332,911, dated December22, 1885.

Serial No.168,213. (No model.)

To all whom it may concern.-

Be it known that I, STEPHEN LANE, Jr., acitizen of the United States,residing at New York city, in the county and State of New York, haveinvented new and useful Improvements in Overflow-Traps for Wash-Basins,Bath-Tubs, Sinks, 8m, of which the following is a specification.

My invention consists of an overflow attachment for wash-basins,bath-tubs, &c., of novel, simple, and efficient contrivance, thatconnects with the basin at the bottom of the same by a trap, so thatwhile it maintains the water at the proper level when the wastepipe plugstops the waste-pipe the basin will empty all the same when the plug iswithdrawn, but the overflow will be sealed with water remaining in thetrap, which prevents the escape of foul odors, so common from thedeposits bodyingin the overflow-passage, all as hereinafter fullydescribed, reference being made to the accompanying drawings, in which hlgure 1 represents a sectional elevation of a wash-basin having myimproved overflowtrap. Fig. 2 is a detail in plan View.

lnstead of attaching the upper end of the waste-pipe a directly to thebasin, I form on or attach to said pipe a cup, 12, adapted to beattached to the bottom of the basin 0 in any approved way, so as to makea watertight joint, d, with lead or packing, and through-the center ofthis cup I make an extension, e, of the waste-pipe up through the bottomof the basin for the escape of the water, and for receiving the plugf,for retaining the water in the basin. 1n the bottom of the basin 0, andsurrounding the waste-pipe extension 6, I make a series of holes, 9,communicating with cup 12, and into one side of said cup I connect oneend of an overflow-pipe, h, rising as high as it is desired to maintainthe water in the basin, and returning by the bend vi to the Waste-pipea,with which it connects by its other end, below the trap j, fordischarging therein.

When the waste-pipe is stopped by the plug f, the pipe h allows freeescape of the water into the waste-pipe after the proper level has beenreached in the basin, and when the plug is removed the escape of foulodors from the overflow is trapped by the water re maining in the cupI), as will be clearly seen.

The overflowh may connect with the wastepipe above or below the trap j,as preferred, and the vent-pipe sometimes used to conduct the gases fromthe waste-pipe up through the top of the house may connect either withthe waste-pipe a or the overflow h, as preferred.

For asimple method of'connecting the wastepipe or and the cup b to thebasin I utilize the extension e for a screw to bind them together, byconstructing it with a head, k, at the upper end and fitting thelowerportion to screw into the upper end of pipe a, or into a nipple, Z, ofthe bottom of the cup in case pipe at connects to said cup by a nipple,as I have represented it in this case.

The basin is properly recessed in the bottom for the head It to set inflush with the surface of the basin, and the passages y, connecting theoverflow-trap and the basin, are made in the head, which is madesufficiently large for the purpose. The holes also serve for theapplication of a spanner for turning the screw.

I am aware that it is not new, broadly, to .l

the combined basin having a series of holes through it surrounding thewaste-pipe connection, the cup I), attached to the upper end of thewaste-pipe a, and adapted to be attached to the bottom of the basin andto receive the water through the holes aforesaid, the overflow-pipe h,attached to the cup and to the waste-pipe, and the headed andscrewthreaded extension-joint e of the waste-pipe, passing through andconnecting the cup and the basin, and forming a separate waste-passagethrough the cup, substantially as described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
